Abstract: 1,140,603. Valves. HONEYWELL Inc. 26 April, 1966 [14 May, 1965], No. 18247/66. Heading F2V. A gas valve comprises a rotatable disc 15 which can be positioned to " OFF," " PILOT " and " ON " positions by rotation of a knob 51. The disc 15 is rotated by a gear-wheel 49 and a T-shaped rod 52 provides a coupling between the gear-wheel 49 and knob 51. The knob is depressed in the " OFF " position to engage the rod and rotate the disc 15. The rod 52 is engaged by lever actuated by a solenoid such that when the pilot flame is lit the rod 52 engages the gear 49. A spring 46 enclosed at one end to the housing and at the other end to the disc 15 provides a load urging the disc to the OFF position such that if the pilot flame fails to ignite or is extinguished, the lever acts on the rod 52 to move it out of engagement with the gear whereby the disc 15 is moved to the " OFF " position. The disc can also be moved to the " OFF " position in the event of fire by making the gear of low melting point material such as plastics material. When the disc has been moved to the " OFF " position by release of the rod, the knob 51 has to be moved back to the " OFF " position before it can be depressed.

Abstract: 895,834. Automatic voltage-control systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 4, 1959 [June 7, 1958], No. 19142/59. Class 38 (4). In a stabilized direct voltage supply system comprising two parallelconnected regulated rec tifiers, one of which is of high power and compensates for low-frequency load variations and the other is of low power and compensates for highfrequency load variations, the power supplied by the high-power rectifier is controlled so as to maintain the output of the low-power rectifier substantially at the centre of its load range. In an embodiment an electronic rectifier 4, having an electronic voltage regulator 5, is connected in parallel with a rectifier 2, having a transductor voltage regulator 3, to control the supply from an alternating-current source 1 to a load 14. A voltage proportional to the load current through the rectifier 4 is developed across a resistor 11, via a current transformer 9 and a rectifier 10, and compared with the voltage of a battery 13. The resultant voltage across a resistor 12 modifies the voltage applied to the regulator 3 from the load 4 so that the output of the rectifier 4 is controlled so as to maintain the output of the rectifier 4 substantially at the centre of its load range.

Title: Facsimile telegraph receiver
IPC: H04N1/16
Filed: 1945-07-27
Abstract: 596,504. Copying telegraphy. CREED & CO., Ltd. July 27, 1945, No. 19294. Convention date, Aug. 5, 1944. [Class 40 (iii)] In a facsimile receiver a rod electrode is mounted so as to swing about an axis parallel to the axis of a scanning helix and is adapted to press an electro-sensitive recording medium against the helical electrode, the recording medium being so mounted that its pressure on the helix is substantially independent of the tension produced in the medium by its driving means. To prevent the rod electrode "bouneing," damping means are provided, and means are also provided to clean the helix, of dust and the like during recording. A rod electrode 19 (Fig. 2) is mounted in the upper ends of two arms 31 fixed at their lower ends to a pivot rod 32 on which by means of a resilient sleeve 35 a mass 34 is eccentrically mounted to balance the weight of the rod electrode and arms 31 so that tilting of the receiver will not vary the pressure of the rod electrode 19 on the scanning helix 13. A spring 30, and/or a weight 40 if the receiver is not liable to tilting, may be added to provide the working pressure between the two electrodes 13, 19. The inertia of the mass 34 damps any vibration of the rod electrode 19 which may occur. In order that the tension of the recording medium 14 may produce little or no effect on the pressure of the rod electrode 19 on the helix 13, it is led from the supply roll (Fig. 1, not shown) over an adjustable roller 18, round the rod electrode 19 and up vertically to draw rollers 21, 22 so that the paths of the medium to and from the rod electrode are in planes substantially parallel to the plane containing the rod electrode (which moves through only a small arc) and the mounting pivot rod 32. In order to clean the helix 13, a cam 47 rocks a spring-loaded lever 46 about a pivot 43, thus intermittently bringing a wire brush 38 supported on insulating material 41 into contact with the helix 13. In order that the recording medium may not get slack, a slight drag is imparted to it by a spring-loaded roller (Fig. 1, not shown) and the adjustably mounted roller 18 causes the forward and return portions of the tape to rub together, ensuring in addition that any foreign matter is removed from the underside of the recording medium. In a modification (Fig. 3) the rod electrode 53 is mounted on horizontal arms 57 urged by a spring.59 into contact with the helix 61, the symmetrical mass 63 serving to damp any vibration of the rod electrode, and the recording medium again traverses substantially horizontal paths to and from the rod electrode. In both these modifications, received signal potentials are applied between the rod and helix electrodes. In a further modification (Fig. 4), a steady potential is applied between the electrodes 73, 76 and the received signals move an armature 69 and hence move the rod electrode 73 and recording medium 14 into or out of contact with the scanning helix 76. Any of the embodiments may be used for either tape or sheet recording.
